Abstract

The invention provides an inorganic zeolite powder containing nano zinc oxide for suppression of sulfate reducing bacteria and a preparation method, which relates to an antibacterial agent and a preparation method. The invention solves the problem that the prior organic antibacterial agent has poor security, poor heat-resistant property, easy decomposition and short service life. According to quality percentage, the invention is made of the zeolite of 50-99.99 percent and the nano zinc oxide solid of 0.01-50 percent. The preparation method is as follows: 1. Preparation of the nano zinc oxide; 2. Mixing and stirring; 3. Extraction filtration, washing and drying; 4. Grinding, calcinations and grinding; therefore, the inorganic zeolite powder containing nano zinc oxide for suppression of sulfate reducing bacteria can be prepared well. With solid-phase synthesis, the invention adopts the nano or submicron zeolite, not only effectively increasing the amount of the loaded nano zinc oxide, but also improving the sterilization effect of the antimicrobial agent.

Description

technical field [0001] The invention relates to an antibacterial powder and a preparation method thereof, in particular to a natural zeolite-loaded nanometer zinc oxide inorganic antibacterial powder and a preparation method thereof. Background technique [0002] In recent years, with the accelerated development of the national economy, the pollution of industrial wastewater, especially sulfate wastewater, has been quite serious. The groundwater of many large cities in my country has been polluted by sulfates to varying degrees. Discharge of sulfate-containing acidic wastewater directly into the water body without treatment will acidify the receiving water body, reduce the pH value of the water body, endanger aquatic organisms, and cause potential corrosion; this type of acidic wastewater will also damage the soil structure and reduce crop yields. Sulfate wastewater has a long incubation period, and although it has the activity of natural reducing bacteria, it has become a ...
